Comparision of digestive enzymes activity in Schizothorax zarudnyi intestine in wild and cultural conditions

There is different between the activity of digestive enzyme in cultural and wild environment. Because of changing available food stuffs.The object of this investigation is deliberation of the activity of α-Amylase Tripsine and Lipase enzymes in anterior, mid and posterior of Schizothorax zarudnyi intestine in cultural and wild environmental. For this reason 12 wild in from 4 groups weighted average number (141.6±6.3, 209.5±2.63, 263.1±9.6, 326.15±26.9) and 13 cultural weighted average number (55.1±5.6) were used. The results showed that survey activity of α-Amylase was higher than other enzymes in both group of wild and cultural fish. The highest activity of α-Amylase was observed in mid gut and the activity of this enzymes had a significant difference in different of segments of intestine (p<0.05) but the significant difference was observed between anterior and mid gut with posterior (p<0.05). The results of deliberation of Tripsine and Lipase enzymes activity showed that the activity of these enzymes were decreased from anterior to posterior gut in both groups of fish.The comparison of α-Amylase, Tripsine and Lipase enzymes activity and average weight of wild fish showed that the activity of these enzymes was increased with increasing of weight.
